Astronomy Difficult Questions - 1145 Words

1. What prominent northern hemisphere star was the first to have its spectrum photographed? 2. An interstellar cloud of gas known as an H-II region is mainly composed of what? 3. What celestial object is known as the morning star or the evening star depending on when it is seen in the sky? 4. Which planet of the Solar System is accompanied by two moons named for the Greek gods of fear and terror? 5. On what kind of diagram are stars plotted according to their surface temperature and luminosity? 6. A common problem with refracting telescopes is a fringe of false color around the image, caused by the inability of a large lens to refract all colors of the spectrum to a common focus. This is known as ______.†¦show more content†¦Syzygy is also the shortest English word containing three ys. 18.) Answer: ~1.44 One solar mass is equal to the mass of the Sun, about 2 nonillion kilograms. If a white dwarf were to exceed ~1.44 solar masses, its electron degeneracy pressure would not be able to support it. 19.) Answer: The Earth and the Sun An astronomical unit is sometimes abbrviated to AU, au, a.u. or sometimes ua. It is actually equal to the semi-major axis (the farthest point; since the orbit is elliptical) of Earths orbit around the Sun. 20.) Answer: Plasma Plasma is usually an ionized gas, meaning that one electron has been taken or added to an accumulation of atoms or molecules. This state of matter, which the founder called radiant matter, was first identified in 1879 by Sir William Crookes inside a discharge tube. It was later renamed plasma by IrvingShow MoreRelated Astronomy Essay1029 Words   |  5 Pageshumans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word â€Å"astronomy† is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night. nbsp;nbsp;nbsp;nbsp;nbsp; Astronomy dates back to ancient times when peoples such as theRead MoreThe Republic By Socrates1591 Words   |  7 Pagescomes at a time in the dialogue being played out in the Republic in which the education of the guardians (especially those who will be the philosopher-kings) is in question. The foundational elements of this education have already been discussed, these being the subjects of music and poetry and rigorous physical training. However, the question remains what other subjects should be added to the education process of the guardians to make them fit rulers of the just city. As Socrates has mentioned earlierRead MoreAnalysis Of SignificanceWill Make You Reevaluate Your Place In The World717 Words   |  3 Pagesthriller follows the story of three characters as they deal with the recent discovery of a supernova. First, there is Miles who studied astronomy but is no longer an astronomy student. He is still passionate about the subject and eager to find a new discovery. H e is the first one to discover the massive supernova. Excited by his find, he calls his old astronomy professor Andrew Miller to analyze his discovery. Before Miller arrives, a woman knocks at Miles door looking for help. Miles helps herRead MoreJohannes Kepler Essay991 Words   |  4 Pagesrevolution. This can be seen as contributing to the development of calculus. Not only did he help the development of calculus, but he calculated the most exact astronomical tables known today. This accuracy did much to establish the truth of heliocentric astronomy, which states that the sun, and not the earth, was the center of the planetary system. Kepler was born in the small town of Weil der Stadt in Swabia, and moved to nearby Leon berg with his parents in 1576. His father was a mercenary soldier andRead MoreJohannes Kepler, The Father Of Modern Astronomy1575 Words   |  7 PagesKepler, the â€Å"Father of Modern Astronomy†, had an enormous impact on different aspects of science and mathematics such as geometry, physics, optics, crystallography and philosophy, eventually paving the way for more like-minded thinkers. His mathematical proofs supporting the heliocentric model of the universe was essential to progressing the scientific revolution. He reflected the Renaissance ideals of education, secularism, and observation while bridging medieval astronomy with modern science. His researchRead MoreA Critical Review of the Introduction (pp.xi-xvi) to Cumont, Franz, Astrology Among The Greeks and Romans, New York: Dover Publications 1960 (1911)1092 Words   |  5 Pagesthe seventeenth century. According to Thomas the heliocentric theory was still compatible with astrology. The Earth is constantly revolving and changing position, therefore new calculations will have to be made all over again. This was difficult, but it was not impossible. 4 Therefore showing how Cumont’s comment; that the planets and their influences made no sense or difference to humanity after this new scientific discovery, can be considered as outdated. Nicholas CampionRead MoreThe Development Of Telescope1641 Words   |  7 Pagesbiggest telescope until 1993. It ranged up to a billion light years; it was the greatest telescope in the world. It allowed human to observe quasar in 1963 and remains the most exploration tool in the world.It is still contributing to the modern astronomy as it works at least for data collection in 290 nights a year. Of course, there are many other waves that cannot be directly observed: some technique must be used to make more observation. In the year of 1937, Grote Reber was inspired by KarlRead MoreAstronomy Lab1648 Words   |  7 Pagesoverview of the solar system.  · 50 points are possible Introduction It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance withinRead MoreChanges Brought about the Scientific Revolution730 Words   |  3 Pagesconfusion between numbers and letters was difficult to avoid, since Roman numerals were the Roman letters. When Arabic numerals were adopted, several advantages had arisen. Solving calculations, especially complex computations, became a process that was completed rapidly. With a place number system, complicated mathematical calculations were easily solved. Because of this, there was an advancement in calculus, which sparked the start of mathematical astronomy. Due to the ris e of calculus, science andRead MoreEssay on The Discoveries of Galileo Galilei910 Words   |  4 PagesThe telescope was invented based off of a â€Å"spyglass† that was created by a Flemish lens grinder. Galileo was a man of many trades; philosophy, astronomy, and mathematics were among his favorites. Before he started studying the skies, Galileo taught math at Pisa and then Padua. After creating his telescope he became known as a hero to many people across Italy and most of Europe. Galileo Galilei was born in Pisa, Italy in February of 1564. As a teenager his moved to a monastery school, and then
